Hi, Just tested now with PIC16F1825 and results are ok. I am attaching the photos and screenshot. I used USB-to-TTL converter from Aliexpress with Silicon Labs CP2102 IC and there is no inversion. Just used voltage divider on PIC TX pin 6, 1k-1.5k to interface with 3.3V level of USB converter. The chip on RHS is PIC16F1825 and on LHS is PIC16F1827. Regards, Awais
-
Thanks. It's lot easier in GCBasic and it reminds me when I started programming in BASIC in 1988 with CASIO FX-802P with very limited program memory. Right now I am missing floating point calculation in GCBasic. Regards,
-
Yeah, it's much better. I am also using SynWrite. See my last post. Regards, Awais

Thanks, Evan. I will test and reply. Just to mention that "MSEG" is the part of replied string from SIM800L and there are three CR and LF in the string. "MSEG" part is between second and third CR and LF. I am planning to use your ring buffer code to receive serial data from the module and save it in a string array, count received number of bytes which will be 57 then process the string array. I did not understand this part "as string * 16". Regards, Awais

Hi, I am integrating SIM800L module with PIC16F1827 using serial port. I want to extract sender phone number and message from the received SMS using non blocking code but getting no idea how to do it. After receiving SMS of appropriate command, PIC will send back the data to the sender, e.g. a count value. The serial data format received from SIM800L module is as follows. +CMT: "+123456789012","","23/10/15,14:51:31+20" MSEG (HEX format with printable characters) 0D 0A +2B C43 M4D T54 :3A 20 "22 +2B...

Hi Rich, Any success? Second, I would like to share a really good Android Oscilloscope. If you can DIY (HS-40X) or buy a ready made (HS502/512). https://www.martinloren.com/ https://play.google.com/store/apps/details?id=com.martinloren.hscope&hl=en&gl=US Regards, Awais

Rick, have you checked the following? Loop back testing (put jumper wire b/w pin 2 and 3) of your USB-to-Serial converter. Usually I use "Realterm" or Arduino can also be used for simplicity. "Hercules SETUP utility" is also a good software. https://www.hw-group.com/software/hercules-setup-utility Check USB-to-Serial converter voltages on pin 2 and 3 with reference to pin 5 (0V). If you can use Oscilloscope then it will be much better. Usually cheap converters do not provide proper voltage levels...

I agree with Jerry. Many years back I made this RS-232 converter using DIP package and this IC needs external 5V or 3.3V supply voltage. Pay attention for common "0 Volt". I think there is power indicator led D1 also on the module. Is it ON? Rich, in your posted photo "VCC" pin is not connected. Check Figure-1 in the following link. https://forum.arduino.cc/t/reading-rs232-with-max3232-module/911558/5 Regards, Awais

Thank you Evan, rest of the GCBasic team and G. C. for your efforts to solve the issue. I will test the code with new timer.h file on PIC16F1827 and will update. Regards, Awais

Hi, I found the following links and the attached file after a quick search. Hope it will help.

Thanks, GC. I missed that underscore mistake. Regards,

I will update after testing the code on hardware. Thanks.

Got it.

I loaded two programs in PIC16 Simulator IDE to see the value of T1CON. File names are self explanatory.

Hi G. C., I will check your code. I tested LED_blink.gcb on hardware PIC and results were good. As per my observation, there is some issue in configuring Timer Control Register. 11:47:30.361 -> T1CON Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 11:47:30.401 -> 11:47:30.401 -> 0 0 0 0 0 0 0 1 Bits 4 and 5 should be 1 for prescale value of 1:8. See my below post. Regards, Awais

Thanks G. C. for your reply. Now there are two issues. First, if I write as follows #chip 16f1827, 16 #option explicit then the code does not compile and gives the following error. Error: Variable FOSC was not explicitly declared Second, without option explicit, it compiles successfully and I am getting frequency of around 40Hz at LED pins. But my target is to get 100msec interrupt at 16MHz internal oscillator. I configured Timer1 control register at bit level using the following link and got the...

Hi Evan, I am programming PIC16F1827 in which Timer1 is used to generate a delay of 100 msec. Code file is attached. First problem is that as per timer reload value of 15536 for 100msec, interrupt is generated at 25msec which I verified also from an oscilloscope at pin A2 whereas the following timer code in mplab generates 100msec interrupt which I verified. void TMR1_Initialize(void) { //Set the Timer to the options selected in the GUI //T1GSS T1G_pin; TMR1GE disabled; T1GTM disabled; T1GPOL low;...

Hi Anobium, Sorry for replying late. I was busy with the job and thanks for the guidance. I don't think that I am so good in programming to accept this challenge. I found the following page from Nick on the same topic. Hope it will also help to someone who is ready for this challenge. http://www.gammon.com.au/lcd With kind regards, Awais

Hi, Recently, I found the following module to make job easy for GLCD. https://www.aliexpress.com/item/MCP23017-12864-128-64-LCD-I2C-IIC-TWI-SPI-Serial-Interface-Adapter-Plate-Board-Converter-Module/32882157852.html?spm=2114.search0104.8.40.6719703cOp3JFM&transAbTest=ae803_4 Is there any example available with GCB to use it with GLCD? With kind regards, Awais

That is not way I would do it. As I am not guess. GLCD_OLED_FONT = 1 this reads the tables called OLEDFont1Index and OLEDFont1Data. Replacing this is one way. | | I am still trying to grab this method. Hope to get success. Regards,

Yes, the message should scroll from right to left but I am surprised that why it is from left to right in my hardware (right one is the first module which is connected to Arduino). I tested Parola library for Arduino and its ok but there are issues of consistency. But with GCB its good. The system is running fine. Now, the orientation and scrolling direction have to be controlled. I will try to understand the routines to tune it for the requirements. Please update here if you come up with the solution....
-
You are right. That is one solution but there are other concerns due to which I cannot rotate it.
-
Thank you. Now, text is scrolling correctly. But in my hardware design the text should be upside down. So, the command should be something similar to define Pset max7219_LEDMatrix_PSet_270 and the first module connected to Nano is the first from right hand side. So, text scrolling should be from right to left. YouTube video link is here https://youtu.be/A6L7K7WLLnU

PORTB.0 = PORTB.0 xor PORTB.0 is giving error. Can you please have a look?

Thanks Anobium for pointing out the .RB replacement. I tried but got same result with error. Original code is different but I want to toggle the output bit, so I used XOR.
