Can the storage in the HyperRAM be automated for some variables at compilation on a STM32H735G-DK Board?

Hello,I am working on the SM32H735G-DK Board and I would like to automate the storage in the HyperRAM for some variables by using the OCTOSPI interface. I have followed the AN5050 Application note about the OCTOSPI Interface to configure the OCTOSPI ...

I can't solve the ADC error descibed in ES0251 - Rev 5 - December 2021. STM32L051R8T

Dear allI use the ADC of an STM32L051. According to the errata, the first measurement is not accurate if the ADC has been idle more than 0.5ms. I can observe the effect if I poll a certain channel.In my application I want to convert 5 Channels every ...

the max frequency of STM32G030x6x8 series CORE

hi,everyone,I'm a new user of the SMT32 MCU, now i'm looking up the datasheet of STM32G030x6/x8 series, In this article， the Frequency of CORE is described to reach up 64MHz on PAGE 1, but on PAGE 11, Figure 11 block diagram, fmax = 56MHz, so what ...

I want to send serial data in Manchester code using STM32H7. Could anyone please tell me the solution? Or if you know an IC part that can be converted to Manchester code externally, please introduce it.

How long does it take to call the interrupt function of comparator?

I tested with NUCLEO-F303ZE (72Mhz clock).I checked the time when comparator makes interrupt as below ------------------------------------------------------------------------------------void COMP7_IRQHandler(void){ DRV_GPIO_Port->BSRR = (uint32_t)DRV...

Start condition for I2C not working.

I am using an STM32F411, and am attempting to use I2C to communicate with an MPU-6050 (relevant datasheet info attached).I've tried to setup I2C in accordance with the timing requirements on the MPU-6050 datasheet: #define MPU6050_PIN_CL (6) #de...

How to port the NFC Reader Library to the STM32 environment?

Hi Community :)I currently using the NXP CLEV6630B RFID reader (chip is SLRC610) for our medical project, and I am using STM32H7 as a host microcontroller.Did anyone do something like that and has ported the NXP reader library to match the desired en...

Configuration of SPI for STM32F429 for writing/reading eprom AT25080/

Hi amazing community... I have a legacy project developed with STM32System workbench..I am trying to configure the spi to working with a eprom memory..I cannot use the cube generator so I have to implement the init of the HAL by myself.I made a test ...

I2C - Adding a registry & value.

Hi, I want to try sending data to a slave consisting of several registries and have seen code example:-uint8_t buf[2];buf[0] = register_addr;buf[1] = data;HAL_I2C_Mem_Write(ftHandle, slaveAddr, buf, 2, timeout);Would this work in practice? As it is m...
