    Hi Gery The tables you refer to: Those pins are dual purpose - for example pg 108 Orange = EN - IN1 pin 9 Direction = DIR - IN2 pin 10 etc If I follow the orange wire of pin 9 on the chip to destination of L298N driver chip I see it labelled there as IN1. This is what I mentioned before, that pins are multi-purpose. If the driver board is L298N the pin 9 = IN1. If a driverboard is DRV8825 then pin 9 is wired to ENable of the 8825 driver chip. My apologies, that the table is not clearer. I can see...

    Hi Gerry I cant answer everything yet in your post. 3:30am and I need sleep I would have expected the direction I/O 10 to if focuser type is L298N or ULN2003 then direction has zero effect. Dir only used for DRV8825, CL42T and TMCxxx chips. Direction is done using a step sequence of pulses. Firmware sends one set to move IN and for OUT it reverses the steps.. Your esp32 chips purchased look like the correct ones. The same ESP32S3 chip is used on all focuser types,CDLSU, ADPT, TMC Except TZT ADPT...

    It is my mistake. The driver board file I sent u is not the one I should have sent (its beta for the next release), The errors were driver_board.cpp:212:18: error: 'T_DrvBrd' was not declared driver_board.cpp:214:18: error: 'T_DrvChip' was not declared driver_board.cpp:219:20: error: 'T_Reboot' was not declared meaning that the text error messages T_DrvBrd T_DrvChip T_Reboot could not be found.. because the text messages do not exist in firmware version xxx_10 Okay, so I have downloaded firmware...

    Hi Gary There is an issue with PushButtonsS3 test program. Within the file there are instructions on lines 39-41. These do not seem to make sense to me given the schematic so I ignored them. Thats because the test program is wrong... I did not make all the required changes and it still has part of myfp2esp32dev code in there. The changes you need are void InitPBpins() { pinMode(PB1, INPUT_PULLUP); // 21 pinMode(PB2, INPUT_PULLUP); // 40 } The pusbutton state should be 1 (high) when not pressed. If...

    If they are both NEMA motors driven by DRV8825. Start with Rotator that is noisy, call it rotator 1 On rotator 1 Swap the NEMA motor to the other one from rotator 2, Is the noise the same No - then motor is the issue Yes - then DRV8825 chip is issue. I have a number of drivers, and amongst them a heap of DRV8825 chips that are noisy. I mean real noisy, like an engine thats about to shake itself apart. No amount of adjustment could stop the noise of whistle sounds. Only replacing the drv8825 chip...
