• In past month STM published new set of tools and software examples that implement HAL (wikipedia: Hardware abstraction layer) on the many of theirs µC. They are calling this set of tools STM32CubeF4. This post is a little public note to myself and all others who are banging or will be banging their heads...
  • my mistake is using adress (0x53 is true) I read wrong it,but now problem is HAL_I2C_Mem_Read(&hi2c1,ADXL345_I2C_Adress1,DATAXL_INC,I2C_MEMADD_SIZE_8BIT,out,2,1000); I want to get all angles at the same time with multiple bytes read , is it true to use DATAXL_INC
  • HAL_I2C_Mem_Read(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData, uint16_t Size, uint32_t Timeout); Since I don't have any I2C memory chip with me, we'll first explore group 1 functions with two following examples.
  • 学会STM32的开发以及USB库、DSP库的使用方法 ... IIC这个程序中,HAL_I2C_Mem_Read和HAL_I2C_Mem_Write这两个函数是如何读写操作呢? ...
  • How to actually do the measurement. Well the answer for every “How to interface this” is in the device datasheet. If you look at page number 15 of the BMP180 Datasheet, there is an algorithm given to do all the necessary calculations.
  • Функции HAL_I2C_Mem_Write и HAL_I2C_Mem_Read предназначены для работы с памятью, и поэтому нет необходимости использовать общие функции работы с шиной I2C HAL_I2C_Master_Transmit и HAL_I2C_ Master_Receive, тем более, что с ними ...
  • HAL_StatusTypeDef HAL_I2C_Mem_Read(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddSize, uint8_t *pData STM32 i EEPROM - odczyt danych w praktyce. Wiemy już jak zapisać dane, teraz spróbujemy je odczytać i sprawdzimy, czy wartości się zgadzają.
  • Toggle Menu. STM32 I2C EEPROM with HAL. 1 minute read. These setup the I2C address, the maximum page size of the EEPROM (32 used here for compadability). along with the timeouts. and the remaining ones...low packet size Result = HAL_I2C_Mem_Read(i2c_port, EEPROM_ADDRESS

사용한 ST7735 드라이버 탑재 80x160 0.96인치 LCD (사용한 LCD 모듈 기준) - 디스플레이 해상도 : 80x160 (드라이버 지원 해상도는 132x162, 128x160)
К сожалению nda не позволяет мне этого сделать, но скажу я вам что у нас несколько тысяч устройств (ПРОМ-устройства) на stm32 в которых используется hal, все прекрасно работает.

Jul 31, 2015 · Here it is. After some email for I2C library for HAL, I’ve made it. I ported my old for F4 to HAL based libraries for F0/F4/F7 series. I added method to read single byte, multi bytes, write single byte, write multi bytes, write/read single byte from/to register which has 16-bit address size.
