Posted on December 30, 2016 at 11:13I am designing a new custom board replicating Sensor Tile.The problem is STM32l476jxx (sensor tile) is not using external crystal for core clock. its uses Bluenrg reset pin on the external clock oscillator input p...
Posted on October 20, 2016 at 11:10While I see no announcement, the following is online: http://www.st.com/content/st_com/en/products/microcontrollers/stm32-32-bit-arm-cortex-mcus/stm32h7-series.html?querycriteria=productId=SS1951 Not only the 400MH...
Posted on January 03, 2017 at 16:18Would like to check out the STM32H7 chips, See if they can do the combination of functions we want, On the F7, we used the cube software, but H7 not supported ( yet ) in the cube.Any thoughts / idea when the...
Posted on January 03, 2017 at 09:26Can I know using a #ifdef if there is a STM32F3 or STM32F4?My idea is to write a cross mcu source.Regards.
Posted on September 23, 2016 at 20:24I am observing an odd behavior with HAL_FLASHEx_Erase. When called to erase multiple pages, the function waits until all pages have been erased before calling FLASH_FlushCaches. I have observed that my simple S...
Posted on December 22, 2016 at 14:14Hi. I'm trying to remap a gpio pin from out to it but the following lines of code don't work.Can someone help me?I need to remap GPIOx, GPIO_Pin from out to in on the fly.void DigitalInOut::SwitchToInput() { HA...
Posted on January 03, 2017 at 09:44I am trying to communicate with a device (a radio module which has inside STM32F103 MCU ) with my STM32f072B disco board using SPI I can program the radio module almost as a standard STM32 MCU the only difference i...
Posted on January 03, 2017 at 10:16Hello All,We are interfacing the OV5642 camera module with STM32f4 discovery board.We are read the camera model no using the i2c protocol. When we are put the break point in the I2C stop condition, we can read the ...
Posted on January 02, 2017 at 19:16I was wondering if I am able to connect an external voltage reference of 4.096 volts to VDDA (to be used as a voltage reference for ADC) without damaging the board?
Posted on January 02, 2017 at 13:31We are using I2C1 in STM32L486 and occasionally we are seeing timeout while calling HAL_I2C_IsDeviceReady,this we are calling before call to HAL_I2C_Master_Transmit_ITThis is happening when USART0 is in use and dat...
