invalid conversion from 'uint8_t*' {aka 'unsigned char*'} to 'const char*' [-fpermissive]

I have tried everything to clear this error. Does anyone know what I am doing wrong and how to fix it? The error if pointing to the HAL_UART_Transmit_DMA call.uint8_t SPI_data[SPI_Buffer_Size] = {};HAL_UART_Transmit_DMA(RS485_1, SPI_data, strlen(SPI...

MX25L51245G external loader & driver for STM32H7

Hi everyone,I'm working on a custom display board with a STM32H7A3ZI MCU. I have the same QSPI Flash than the STM32F769I-DISCO board, which is the MX25L51245G, except that I use the 16 pin package for my custom board. The H7 has an Octospi interface ...

Incompatibility in CAN implementation between HAL and SPL due to possible bug in HAL

HiWe are trying to communicate between an F407 Discovery using SPL's CAN implementation and F756 Nucleo running HAL's CAN implementation.Here is the calculation for time quanta and Baud rate...Baudrate = 1 / Nominal Bit TimeNominal Bit Time = 1 x Tq...

For interrupt priorities set using the STM32IDE CubeMX, where are the auto-code generated HAL_NVIC_SetPriority() calls located?

I could locate the HAL_NVIC_SetPriority() calls for DMA and EXT1 Interrupts in main.c as shown below.I could not find the  HAL_NVIC_SetPriority() calls for RTC, USART & Timers - TIM4, TIM5, TIM6, TIM7. Where is the interrupt priority for these periph...

stm32f4 family gpio boundary address

helloi'm having a question. why gpioX boundary address(range) is 1kb ???according to datasheet, GPIOA's boundary address is 0x4002 0000 - 0x4002 03FF.but offset for register to be set is 0x00 - 0x24. i think that using 1kb to cover that range is inef...
