Receiving a burts of data from SPI using DMA

Hi, I am using an STM32f407VGT MCU and I am trying to receive a burst of data of 112 bytes from SPI1 and storing it in an array buffer, initially set with all its elements to 0.According to the RM0090 TRF this should be easily done with the DMA, but ...

TSL (Touch sense) - troubleshooting / improving an interlaced linear sensor

I have designed an STM32F04 based board with a shield, 4 touchkey sensor (round electrodes with a 10mm diameter) as well as 2 linear sensors. These are using the 3 half-ended electrodes interlaced sensor sensors as described in AN4312. Some things re...

How to correctly set up a micro second timer?

Hi there.I know this question is already asked, but the topics I've read didn't worked for me, so I'm writing this in order to study mi concretely case.I'm setting up my timer using TIM1 with the next parameters://Prescaler for 1 us uint32_t Presca...

Setting TIMER as 16MHz [STM32]

Hello,I want to get timer frequency between 16MHz to 20MHz. So I picked the TIM4 and set it with internal clock. Based on the datasheet (STM32F767), the timer belongs to APB1 bus. When I set the main clock frequency as 216Mhz, I expect to get 108MHz ...
