I have sigma delta 16-bit ADC enabled. It works great with regular interrupt. No problem there, but when I'm trying to use DMA with Sigma Delta ADC, then nothing happens. It will only be zeros.I have 9 SDADC zero referenze on SDADC1, 3 SDADC zero ref...
When flashing a bin file to a blank/erased STM32G070 the --reset option does not consistently reset the processor after flash. The first couple times I did this it worked. Now it is not.A snippet of the output from a failed example using the command ...
HelloOur new product use a STM32F427 and a ADC(AD7768-4) the data input connection is the SAI(serial audio interface). The STM32F4 SAI mode is the slave mode.The ADC sends SAI_SD signal and SAI_FS at rising edge.Therefore, we think that the STM3...
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...
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...
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 ...
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...
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...
Hi There,I am working with a MCU STM32F405VET for any particular purpose. Lets a at this time firmware code has burn on MCU. Lets talk about HW issue.Take a look the datasheet here https://www.qdatasheet.com/datasheet-download/190671/1/ST-Microelectr...
