I am trying to communicate with a spectrometer sensor using SPI protocol. With SPI default settings, I am using both arduino and Stm32L476 nucleo boards. (8Bits, MSB First, CPOL Low, CPHA 1 Edge).I read multiple registers from the sensor using both a...
I am working on register level programming, and I have gone thoroughly the reference manual it just contains about the features of the peripherals and registers and something about its working so how can I program if it does not contain the procedure...

STM should really post their code to handle FPU context saving and restoring BECAUSE their clients have been asking for over a decade!!!One user stated "the time for a full FPU state save/restore is quite long. A pair of vpush {s0-31}/vpop {s0-s31} t...
when power is supplied, the discovery board's LD2 is powered on but the main COM isn't powered on, what is the problem?
Among STM32 boards, I would like to recommend a board that includes an interrupt 2 or more pins, I/O (Analog) 20 or more pins, MCLR (reset), PWM signal (more than 2 pins), AVdd, AVss, Vss, RX, TX, ICDCLK, and ICDDATA pins. This is the first board I'm...
I have the problem on my STM32H753, that the IDLE-bit is set when transmitting. On the manual it says: The IDLE bit is not set again until the RXFNE bit has been set (i.e. a new idle line occurs).The RXFNE is never set (actually on CubeIDE this is sh...
I'm using the UART (USART5) with RS485 and I have enabled the read to be on also when sending. I need to read back the data that was sent to see if it is correct. The problem is, that I do not receive what was sent. But if I send the same data from o...
