Resolved! Why is Sigma Delta ADC 32767 at 0 volt?

Hi!I'm trying to read Sigma Delta ADC for 16-bit. It works, but it seems that everything is reverse.For single Sigma Delta ADC I get 32767 (0x7FFF) when I apply 0 volt.For differential Sigma Delta ADC I get 65553 (0xFFFF) when the difference is 0 vol...

STM32H750VB Hangs while accessing data using MODBUS protocol

Hi I am developing a dispenser. The dispenser has a CPU, Keypad, Pulsar and Display each board developed with STM32H750VB. In that I have done the coding for MODBUS in CPU. While the machine is IDLE the MODBUS works correctly and i am able to r...

Resolved! STM32G0 Variable square wave generation

Hi all, I'm using a NUCLEO-G071RB board and I simply want to generate a variable frequency square wave. I started from project TIM_OCToggle found on the examples.My problem is that TIM1 channel 1 has a fixed frequency and even if I change it through ...

My device is setting watchdog during powerup.

Dear ST community,We are using STM32L152VBT6-LQFP100 Pin IC in our device. we are using it for a long time. recently we observed that our 2 boards are setting watchdog during Powering the Board.the boards are going in the loop of watchdog reset. what...

Resolved! STM32 SDIO 1 bit + DMA double writes (also 4 bit isn't working)

Hi all!I'm trying to configure SDIO in several modes:1 bit1 bit + DMA4 bit4 bit + DMAOnly 1 bit is working for now. When I enable DMA in 1 bit it double writes things into my files. 4 bit mode on the other hand mostly gives me error " FR_DISK_ERR" af...

Resolved! Hi, I have problems starting the program after a power reset. The program does not always start this way. Running through debag increases the startup percentage, but does not make it 100%. How can I fix it?
