I'm sending and trying to receive 5 bytes. If I run the peripheral at 3MHz all is well. If I run at 6MHz I miss receive bytes. If I break and inspect hspi4.RxXferSize I can see this will be stuck at 2. The TxXferCount has counted down to 0, and so th...
Hi guysSo I am developing a small PWM generator around the F334R8, it's overall extremely simple. All the work is done with another MCU sending data on SPI.On the F334R8, an EXT interrupt is called when the CS line is pulled down. From there the F3 l...
Hi,I wanted to Erase and write data to select Flash memory location.I have Nucleo-L4R5ZI kit and have example Flash erase code available for L4 series which I ported to R5ZI.As you can see, the example code has two portions:Erases the page(s) which w...
On stm32L010RB datasheet and on STM32L0x0 reference manual (RM0451) I found 512 bytes (category 5 devices) place at 0x0808 0000.Using STlink utility program, erase sector shows 2 banks of 0xc00 bytes starting at the same address, for a total of 0x18...
In the STM32G4 reference manual, section 30.8.15 has TIM16 and TIM17 OR1 at address offset 0x50. This register is used to enable the HSE/32 input to TIM16/17 for measuring the frequency of the HSE clock. In section 30.8.22, the register map summary...
Hi, I am using stm32l432kc nucleo and BMP280 sensor with I2c communication.During the debugging I realized that the data from the sensor is not updating, always 2481 (temp32 variable).Could you help me in this topic?Thank you in advance.Info:Used dri...
I am trying to use CAN on STM32743ZI eval board. . I am able to transmit and receive data in loopback mode successfully without any error but in normal mode I am getting transmit errors. The FDCAN interrupt registers are 0x31800000. It means that pr...
