Resolved! Effect of using Crystal/Ceramic Clock option with MEMS oscillator
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...
How do I wake from Stop mode using UART?
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...
STEVAL-IHP005V1(STM32F103x, ST7540) inquiry
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...
Troubles in Programming USART of NucleoF429
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...
Has anyone ever had trouble with STM32 communicating info to another processor through the SPI?
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...
STM32L496RGT6 ADC
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...
ADC on STM32L471RGT6 only returns 8 bit values
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...
SPI communication with ADS1256 ADC data reading
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...
configure system clock using registers for stm32f030k6t6
I need to configure the system clock using registers for 48mhz without external crystal, I already have it configured and tested with stmcube ide manager, but I need to decrease the flash memory and ram, as they are critical.i have this configuration...
