ADC Advice

Suppose you want to get the max sample rate out of the ADC and you can not use DMA, how would you do that?

'F3 - RM316 COMP registers documentation

Please consider these modifications to RM0316:Also, please unify COMPxINSEL/COMPxINMSEL in that chapter (best by removing all instances of COMPxINSEL altogether - note, that in the registers table, the COMPxINPSEL bits are incorrectly marked as COMPx...

CAN2 peripheral configuration

I have this code attached which is configured to run both CAN1 and CAN2 peripherals however the TX functionality which is what I was trying to use is working on CAN1 but not on CAN2 (trying to send a packet using ADDmessage TX routine), I double chec...

I would like to create a 24-bit ADC using DFSDM. Application notes mention this exact goal and describe using an external modulator from a variety of companies including ST. However, I cannot seem to locate any external Sigma Delta modulators intended

for over 16 bits.

What is the difference between the use of GPIO_EXTI and a TIMER with Input Capture? Which are their best application respectively? Regards

STM32F723E-DISCO WM8994 audio codec

Hello,I try to use STM32F723E-DISCO to create guitar sound effect processor.At the begin I try to configure WM8994 codec to work in a simple loopback application LineIN to LineOUT (with small buffer in STM32 RAM memory). But without any positive resu...

H750 value line

I'm starting a project with stm32h750vb. Is it really worth it? I see that people are having problems with ADC, SDMMC, I2C. Are these problems inevitable with the H7 family?Btw, I want to make a 2 layer pcb with the h750, any advices?

STM32F373 ADC values are incorrect (between 1-20% from measured pin voltage)

My MCU is the STM32F373VCT6. I am performing a single scan of several ADC channels (DMA). The values returned are generally in the ballpark of where they are supposed to be but some values are very off from the measured pin values. I believe my confi...

HOw to set ExternalTrigConv for SDADC_HandleTypeDef structure of ADC's variable in my stm32xx MCU application?

I want to use two SDADC_HandleTypeDef variables in sigma-delta ADC-s differential mode triggered by timer TIM3 for example?
