Hello, i read the UM2577 pdf, the user manual for the Discovery kit with STM32G474RE MCU (B-G474E-DPOW1 board). On page 29, chapter 13.3, an audio class-D amplifier example with separate application note is mentioned. Where can i find this app note a...
I set up Timer1 Ch4 and Timer2 Ch4 to toggle their Pins (PE14 and PE11) on Capture Compare. I use this as a step signal for stepper drivers with high microstepping (256x). I recognized that when I activate the interrupts to count the number of pulse...
Is there an LL example to enable the backup ram. This doesn't work: // Enable PWR clock LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_PWR); // Enable Backup ram clock LL_APB1_GRP1_EnableClock(LL_AHB1_GRP1_PERIPH_BKPSRAM); LL_APB1_GRP1_Enabl...
During ESD testing, we are noticing issues with our ADC values getting stuck.We are using STM32L475VGT6.No permanent damage has been observed. Resetting the MCU always results in normal behavior. We are using DMA to load all ADC channels. We are ca...
Hi everyone,I work on Data Acquisition System project. Our main controller is STM32F765VG. We used ADS131A0x A/D converter (by SPI) to sample input signal in our previous version. Now we want to replace ADS131A0x with ADS1274 (because of its higher s...
Hello I am exploring the ADC functionality of STM32F103C8T6. I connected a potentiometer to PA2 and connected an LED at PA0 as indicator. The indicator shall get activated once the potentiometer reaches the set threshold. I tried to set the maximu...
Can STM32 able to replace an old peripheral that required 8-bit parallel data bus and communicate between 8051 MCU. We can't modify the 8051 MCU and we can't use FPGA too. I know FSMC is very close solution to my case but in my situation, the STM32 i...
Hi everyone,I am trying to use CubeMX and the HAL library to get two STM32F411E discovery boards to communicate with each other via SPI. In a first step I am simply trying to configure the master correctly. I want to drive the NSS pin of the slave wi...
Hey guys, just having the hardest of times changing clock frequency to 80MHz for the system clock and 43MHz for the ADC clock. Every time I try it seems the writing function to registers gets disabled such as RCC->AHB2ENR trying to enable GPIOA and A...
Trying to setup communication between stm32f407VG discovery and nrf24l01 via SPI. It looks like reading data from registers is going fine, but there is trouble with writing to them because, doesn't matter if i write something to register or if I don'...
