I am using STM32F103VGT chip and custom PCB with USB, graphics LCD (FSMC mode), RTC, CRC, ADC, TIM2, TIM4 and UART3 (DMA/IRQ).When I added SDIO, one data line (poling, IRQ or DMA) and FATFS, I noticed, that after mounting, reading and writing to SD c...
Hi,in RM STM32G4 (I use Rev. 7, page 1882, Figure 648 "Transfer sequence flow for I2C master transmitter for N>255bytes":The "RELOAD=0" info in last box at "N<256" is wrong.It must instead say RELOAD=1, AUTOEND=1 (otherwise Stop bit will fire immedia...
I need to have wifi connectivity on my B-L462E-CELL1 wifi board. I am using L462_TCP_Echo_Client app as my starting point. I am using USART2 and here's my initialization code:void MX_USART2_UART_Init(void) { /* USER CODE BEGIN USART2_Init 0 */ ...
We have a project on an STM32H750 using FreeRTOS and I am trying to access an I2C device after the peripheral inits but before the FreeRTOS init and scheduler start in Main.c but I get no interrupts from the I2C port. I have checked that the interrup...
Is it possible to flash the internal memory of a blank STM32L496ZG through USB? The device has Boot0 pulled down to GND, but all the memory banks are blank, from the application note it's unclear whether the MCU executes the embedded system bootloade...
Also, please add the details of bootloader entry through empty FLASH for Cat3. into RM0440.Thanks,JW
AN2606 Rev 55 Page 241/432 says "... bootloader is activated by applying Pattern 6... Table 2"AN2606 page 27/432 Table 2, Pattern 6. Boot0(pin) = 1, nBoot1(bit) = 1, nBoot0_SW(bit) = 1Boot0(bit) = 0, nBoot1(bit) = 1, nBoot0_SW(bit) = 0Other two cases...
Does anyone have experience running CANopenNode together with FreeRTOS?Is it enough to use CO_LOCK_CAN_SEND, CO_LOCK_OD and CO_LOCK_EMCY when accessing the OD variables from other tasks?
Design phase of project and looking to add self test to a project using a STM32L476xx.STM32-CLASSB-SPL looks like the best way to achieve this.Can't fathom from the literature if the STM32L4 is compatible with these libraries.I fear it isn't.
