I want to use CAN Bus in STM32F042F4 (TSSOP20). In the data sheet it says, CAN_RX on PA11 Pin 17, CAN_TX on PA12 Pin 18.When trying to configure in CubeMX, CAN function is greyed out and the pinout has not PA11 and PA12. Isn't it possible to use CAN ...
I am currently working on a project to program a PLC. This one already has a program to control its operation. We are using the Nucleo board STM32F302RBT6. The goal is to extend the program to be able to integrate the uart communication. Unfortunatel...
Hello I m trying measure adc conversion time , I look datasheet , f_adc=37 Mhz(for fast channel) with 12 bit resulation, 4.10 MSps , so ı use f_adc=32 Mhz(for fast channel) with 12 bit resulation, 3.54 MSps should be, but I m not measure 3.54 MSps,I ...
I am having issues getting the status flag polling mode to work when I try to poll with a QuadSPI command that uses all four data lines for the instruction. When using a command with a 4-line instruction in this mode, it polls the first command corre...
Hi, I am looking to read 16bits which are split between port A and B on an interrupt hooked up to exti0. I *seem* to have the dma working and see the expected data at DMA completion (interrupt). However the DMA controller does not react to the interr...
Hello, I have a Nucleo L476RG which I'm using for different projects, and I never gave an importance to the offset addresses that are written before every register in the reference manual.Can anyone explain to me what are theses offsets.
Hello. I'm struggling with DMA on that specific MCU. I'm using MEM2MEM to transfer data from RAM to GPIOD, triggered by TIM3 interrupt. Here's my init code:void MX_DMA_Init(void) { /* DMA controller clock enable */ __HAL_RCC_DMAMUX1_CLK_ENABLE();...
As reported here, this is obviously incorrect.Also, this has been already reported by Uwe Bonnes for 'F411/RM0383, which has indeed been corrected in the registers description, but the GPIO register map still contains the incorrect value. So, could S...
The output pin in question can be configured as LPTIM1_OUT and I know how to configure the LPTIM1 but I'm afraid I'll endup with LSE/2 as a clock. I need the LSE clock source to be connected to that output pin 1:1.Besides using the LPTIM1 isn't there...
I'm new to the STM32Cube series, and I'm using the STM32Cube MX L4 chipset. I believe I've done everything that online tutorials, examples, and the actual specs demand, but when my code issues HAL_CAN_AddTxMessage, my ISR never gets called. What am I...
