STM32F103 SPI peripheral driver

Hey guys I am having one issue, with the stm32f103 SPI peripheral. I have developed my SPI bare metal mode(spi_mast_tran_byte(), spi_mast_recv_byte() : see pitchers below) and w25q128 flash memory in which I am reading its JDEC ID which is at address...

stm32f746disco board repair

hi,i have purchased the stm32f746 disco board recentlythe disco board stlink connection is in fail, after the i have shorted 5V - GND (big big big mistak..)i found that this led(LD7) control is in charge st-link mcu (stm32f103)LD7 Red LED is toggled ...

Region RAM overflowed by 56520 bytes error?

My program does not fit into RAM region as stated in the title. However, I need to fit it somehow. How can I do it? Is it OK if I use SDRAM? Or how to decrease the usage of RAM?Btw, my board is STM32F746G-DISCO. Where can I find information about SDR...

Merge the two half-duplex I2S in STM32F07X to 1 full duplex I2S

I need to use the I2S of uC to communicate the Codec with the full duplex mode.Can I use the two half-duplex I2S in STM32F07X (e.g., STM32F071CBT7TR) to get that? I know that in the STM32F4 series, this function can be achieved with two half-duplex I...

Remove alternate function of single TIM1 Channel outputs and get the control over these pins by GPIO on the fly and take the alternate function back on the fly.

I 'v been driven creasy since some days, cause I did not find a way to switch off the PWMs at one channel of timer 1 ( CH1 an CH1N ie.) in order to use these pins controlled by normal GPIO commands on the fly,while the other channels shoud work aga...

Does any version of OpenSTLinux fit onto STM32H757XI?

I doubt it will fit, but if someone knows that it does, that would open up some opportunities.

Does STM32U585 support DMA writes to internal flash?

Hello,I've been unable to determine if it's possible to use the DMA to write data from internal RAM to internal flash on an STM32U585 device.I've consulted the following, but don't see a clear answer:https://www.st.com/resource/en/application_note/an...

Is anyone done USART in STM32L4R9I-DISCO Discovery Kit please share ... I have trouble doing LPUSART

UART_HandleTypeDef hlpuart1;///init///hlpuart1.Instance = LPUART1;  hlpuart1.Init.BaudRate = 256000;  hlpuart1.Init.WordLength = UART_WORDLENGTH_8B;  hlpuart1.Init.StopBits = UART_STOPBITS_1;  hlpuart1.Init.Parity = UART_PARITY_NONE;  hlpuart1.Init.M...

Using HAL UART, I can't receive a ~20 byte string at 115k, the string is variable length so I have to read character by character but the routine misses characters. Am I correct to think that the HAL routine is too slow to handle this?

Best MCU for HID connection, with digital & analog ports, specifically for ambient light sensors?

Hey, I'm making a school project where the goal is to control an external PC monitor's brightness with an ambient light sensor. The MCU needs to have an analog port to connect a potentiometer, and digital ports to connect a digital ALS. Currently I'm...
