MBB posted a comment on discussion Help
After I sent the above, the ultrasonic sensor stopped working. Further troubleshooting showed that I need to add this to my code: comport = 1 Now everything is working. In the help file under HSerReceive there are the following statements which seem contradictory. "comport = 1 '(1|2|3|4|5)Not needed unless using multiple comports in use" I'm using Port C.7 for UART_Rec and PortC.6 for UART_TX (18F4550). Only one comport. Since it is not needed why do I need it? "The subroutine HSerReceive can get...

I found a solution to the above problem. I changed from 48 MHz to 8 MHz. BUT I also had to change this: HSerReceive Frame_Header HSerReceive Data_MSB HSerReceive Data_LSB HSerReceive Check_Sum to this: HSerReceive xx ; xx and yy are dummy bytes HSerReceive yy HSerReceive Frame_Header HSerReceive Data_MSB HSerReceive Data_LSB HSerReceive Check_Sum I don't understand why I needed to read xx and yy to make it work. The data sheet does not require them.

I just added this to my program #define CHECK_USART_BAUD_RATE When I compile it I get this: Error: Big error in baudrate - percentage error = 75 @ 16800

Are you getting LCD display? The 18F4550 shows the 10 for Data_MSB, 10 for Data_LSB, 10 for Check_Sum and 2570 for Total_Distance on the LCD. Does serial sent work? This ultrasonic sensor responds with out being sent any commands. So, I tried this UART controlled Bluetooth device https://www.sparkfun.com/products/23287 With this device the 18F4550 sent and received data correctly i.e, both the LCD and logic analyzer read the data. I was able to send data from my cell phone and see it on the LC D...

In the include file glcd.h, it has this code for the2in13 and 7in5 e-paper displays: Ifdef GLCD_EXTENDEDFONTSET1 then GLCDCharCol3 = GLCDCharCol3Extended1 GLCDCharCol4 = GLCDCharCol4Extended1 GLCDCharCol5 = GLCDCharCol5Extended1 GLCDCharCol6 = GLCDCharCol6Extended1 GLCDCharCol7 = GLCDCharCol7Extended1 End If The Ifdef and End If do not have the # sign in front.

Thanks for the fast response. Does anyone have a link to an e-paper display that will work with GCB?

I have this e-paper display: https://www.seeedstudio.com/Grove-Triple-Color-E-Ink-Display-2-13-p-2889.html?queryID=7ea48faba49bb43929b744ee897a794d&objectID=2889&indexName=bazaar_retailer_products This display uses a UART interface. GCB supports a SPI interface. Did I buy the wrong display or is there a way to make this work with GCB?

Are you using this device as the I2C master? I'm using the device as a slave. How does 0x40003588 relate to a 7 or 8 bit addressing? 7 bit are range 0 to 127 and 8 bit range is 0 to 255. To get the 8-bit Write/Read you shift the 7-bit I2C address left one bit. I don't know what to do with 0x88 in the base address. 0x88 = 136 decimal = b1000 1000. When I shift it left it becomes 1 0001 0000 = 272 - A word value. So, does the 0x35 become 0x36? Or do I shift the whole base 0x40003588 making it 80006B10?...

I'm using an 18F4550 with version (0.99.01 2022-01-27 (Windows 64 bit) : Build 1073). The chip (TMF8820) I'm using has an image file that needs to be loaded. This image file has 2476 elements in it.

Isn't an answer of 0 the wrong result? If you did divisions and kept reducing the denominator, your answer would keep increasing. For example: 10/1 = 10 10/0.1 = 100 10/0.01 = 1000 10/ 0.001 = 10000 10/0 = ? (infinity or undefined? An answer of zero seems completely wrong.

I'm using Great Cow BASIC (0.99.01 2022-01-27 (Windows 64 bit) : Build 1073) with an 18F4550.

I got 0 for AA, BB, CC, and DD. Since division by 0 is undefined: Shouldn't the...

Thanks William that solved it. Anobium, The Help file doesn't mention it but It appears that this function uses the Compass coordinate system. Is that correct? I would suggest the Help file specify if this function outputs degrees based on the Cartesian Coordinate system or the Compass coordinate system. To me, it looks like the Compass coordinate system.

Is there a way to indicate when a multiplication of 2 variables causes a long variable to overflow? For example: Dim xx, yy, zz as long xx = 70000 yy = 75000 zz = xx * yy ;should = 5,250,000,000 which is greater than 2^32. How would I know zz overflowed?

I'm using an AHT20 Temperature/Humidity sensor. See page 8 of https://cdn.sparkfun.com/assets/d/2/b/e/d/AHT20.pdf The temperature section is working but I get humidity values greater than 100%. I found this code for the humidity calculation on a web site. /* Extract 20-bits of humidity data */ uint32_t reg_humidity = regs[1]; reg_humidity <<= 8; reg_humidity |= regs[2]; reg_humidity <<= 4; reg_humidity |= (regs[3] >> 4); *humidity = (reg_humidity / 1048576.0); Can anyone translate this into GCB?

In the maths.h include file is the Atan function which is on based on Roman Black's formulae.

The Function uses this: Dim uxvector, uyvector, degree as Integer If this is changed to: Dim degree as Integer Dim uxvector, uyvector As Long the range increases from -1456 and 1456 to -32768 and 32767.

I figured out most of this problem. The GLCD_RESET does not go directly to the GLCD. It goes to Pin 7 of the ATSAMD09D14A-MU chip that is on the GLCD board. Pin 7 which is labeled TFT_RST is an active low. I changed the HI2CSend 207 to HI2CSend 206. This puts a low on pin 7. Now all the switches cause a read out on the display EXCEPT Button B which causes the display to go white and stay white even when other buttons are pressed.

I downloaded 98.06 and my program works. I guess something did get corrupted in my 98.05. Thanks for your help!
-
The above source code is good for 98.04 and bad for 98.05. To make it work for 98.05 start by removing lines 264 - 298, 224 - 234, and 95 - 97. Then you might have to remove more until it works with 98.05.
-
I forgot to mention: I've added many more lines of code to the attached program since my first post. It still works with 98.04 but not 98.05. Simply removing GLCDROTATE Portrait_Rev as I did in the first post will not make it work with 98.05

Are you aware that this GLCD uses 4-wire SPI? I was looking at the ST7735R Data sheet. On page 25, figure 8.4 is the timing diagram which shows the D/CX (GLCD_DC) pulse.

At the bottom of page 33 it says " D/CX is sampled when first rising edge of SCL (3-lines serial interface) or 8th rising edge of SCL (4-lines serial interface).

By RESET I assume you mean : #define GLCD_RESET portC.6 This goes low for about 750 usec and then about 4.7 seconds later I see the clock pulses. The Data pulses start at about 6.4 seconds after the RESET pulse. But the GLCD is the same as before. I am using the code you posted.

On my O'Scope I see the Clock, Data, and CS pulses so the 18F4550 is sending the data. The GLCD remains a blank screen with a white background and the backlight on, i.e. the GLCD is not responding.

I have a follow up question. The above response says: "So the resulting byte will be the equivalent of RR left shifted twice then ANDed with 0b11111100." I don't understand why the "then ANDed with 0b11111100." is needed. For example: If RR = 43 = b101011, then left shifting twice and adding 0, 0 at the end gives b10101100 =172. ANDing this with b11111100 gives: b10101100 =172 b11111100 = 252 --------------- b10101100 = 172 the same number I started with before ANDing. Did I do this correctly? Is...

I'm using this Magnetometer IC: https://cdn.sparkfun.com/assets/2/2/4/d/6/MLX90393-Datasheet-Melexis_revision_003.pdf On Page 17, in the Read Register row they use this terminology {A5…A0,0,0} Does anyone know what {A5…A0,0,0} means?
