How the hell it makes sense to have 2 UEVs per period in center aligned PWM mode and not be able to choose which one generates request for DMA and update of registers. For an interrupt it's possible to choose if underflow or overflow events generate ...
I have a board with an STM32L0 part that uses an 8MHz MEMS oscillator as the external clock source. I recently observed that using the Crystal/Ceramic option appears to make the SYSCLK run at half the expected rate. Using the correct BYPASS option pr...
Hello all,After successfully entering Stop mode with my STM32F051, I cannot wake it up. I have referenced this article heavily, but cannot get it to work for me (I see that it is for an F072B): https://github.com/STMicroelectronics/STM32CubeF0/blob/m...
Hello, I am a student studying stm32. I bought that module. I want to modify the source code in CUBEIDE. A part of the PLM stack folder is in the form of an object file. Can I get the file in c code?? I don't know the exact email address, so I'm post...
Hi All, I am new in ST microcontrollers. I tried to get messages from the USART module of NucleoF429. i follow the steps in this article: STM32StepByStep:Step3 Introduction to the UART - stm32mcuI used many serial monitor tools such as TeraTerm but I...
I have an STM32F101V8 communicating with a AT91SAM9260. The Atmel is the master to the STM32. Upon start up, our device checks for communication between these two processors, it does so by using a set of samples. The Atmel sends the samples, the STM3...
I'm having serious problems with the ADCI have the voltage I'm reading going through a 47K/100K voltage divider which feeds into an op-amp configured with a gain of 1 and then to ADC1Ch15 on PB0. VSSA is supplied from an external precision voltage re...
snippet from main code-> uint32_t a=0; uint32_t ADC_VAL[100]; ADC_VAL[0]=0; HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&ADC_VAL, 1); HAL_Delay(10); a=ADC_VAL[0]; <- set a breakpoint at this point to view the value in 'a' <- static void MX_ADC1_Init(v...
In my project i have interfaced the STM32 nucleo-f446re dev kit with ADS1256 and when i trying to read the data there is no sclk ticking like transmitting 2 byte of data in logic analyzer there is no data transmission as well as no proper sclk tickin...
