I am using a STM32L431KCU6 microcontroller and reading data from I2C every 90ms. I would like to implement a sleep mode to achieve lower power consumption, I am using timer6 which generates an interrupt every1ms for system run time. I was thinking I ...

Hi, I'm attempting to use UART3 on a STM32L431CC to transmit 9 bit data, I've created the following code after reading https://community.st.com/t5/stm32-mcus-products/9-bit-uart-transmission-stm32-cubemx-hal-driver/m-p/327138 With the code below I a...

I’m experiencing an issue while developing firmware on a STM32L431CCU6 connected to: Xbee module (XB3-24Z8CM-J) via UART1RS485 driver (ST1480ABDR_ Via UART2 HAL_NVIC_SetPriority(USART1_IRQn, 0, 0); HAL_NVIC_EnableIRQ(USART1_IRQn); HAL_NVIC_SetPriori...

Hi all, I'm trying to receive UART data from an xbee module, I've noticed the xbee is sending out the data correctly (using a logic analyzer) however the STM32L431KCU6 is not receiving this data properly and instead seems like the data is being buffe...

Hi,I have attempted to follow the AN5201 application note page 26 to configure the IIS2DLPC accelerometer to generate an interrupt at every threshold however this interrupt is never generated. I have tried to print the value of SIXD_SRC register and ...

Hi, I've tested your solution and it seems to work fine however it is only sending the data at every other request would you know any other way of setting the 9th bit? I've tried changing the variable type to be uint8_t and the data(wrong) is sent ...

There wasn't anything wrong in the configurations, The problem was that somewhere in the code (still need to find where) the xbee reset pin is being pulled low by the RS485 code in the while1.

Hi Karl, Thanks for your reply, I've noticed your example uses DMA and I was wondering if this is necessary? I was trying to keep the code as simple as possible and achieve the result. However if it is your experience that I cannot achieve the result...

Hi DeLorean, HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4); was already configured in the IOC file but I have tried placing it before initializing the priority levels and that didn't have any effect. Do you have any other suggestions? Kind Reg...

Hi karl, I've solved the issue by shortening the ISR, I'm now filling a buffer until 1ms is elapsed since the last received byte and then performing all checks in while1. Thanks for your help anyways
