HI I have problem during the programming with HAL_I2C_Slave_Receive_IT(). At the end of the receiving without error, the HAL calls HAL_I2C_ErrorCallback(), instead of HAL_I2C_SlaveRxCpltCallback(). The error status is AF ( NAK received ). On the othe...
FolksI have set TIM2 in center-aligned PWM mode as well as a timebase ISR in which I just toggle the LED (for inspection and better understanding of the operation, otherwise to be replaced by an ADC activation, etc.). Thus, each edge of the LED (pin)...
I want to use same pin for SPI MISO and GPIO Interrupt.When I need to take data from SPI BUS then I want touse it as SPI MISO else want to use as GPIO Interrupt. How can I use same pin for both functions?
#error "Define according the used Cortex core ARM_MATH_CM7, ARM_MATH_CM4, ARM_MATH_CM3, ARM_MATH_CM0PLUS or ARM_MATH_CM0"I was using below boards and generated the source code by MX. But above error doesn't understand me. Target: STM32F302R8TxExtensi...
My STMF103 user interface processor needs two modes of operation. One needs to be as fast as possible updating the TFT or TX/RX data, and the other can be slower when it is just monitoring keys and switches. To save power I was thus thinking of us...
We are using the STM32L476VG Discovery Board and are trying to use the SPI 1 interface. I generated the code through CubeMX with pins PA5, PE13, PE14, PE15. After the code was generated I tried placing this example code into the while loop: HAL_G...
In my debugger settings I got there is some SWO frequency difference means before 2 or 3 days its frequency value is 10Mhz but now it is only 2Mhz and from last days I have getting some errors. So plz tell me that such errors are coming due to this ...
Hi everyone,I recently found myself having spent a lot of time working to get I2C to work on the STM32F103RBT6 (the problem: I2C begins life in the BUSY state).This is apparently due to an ADC noise problem, as described in this errata (p. 26):https:...
Hello, STM32F407vg. I am looking for some help in using a flash file system (faftfs) on SPI based NAND Flash. Are there any examples or demonstrations that I can look for to start with?
Hi,my first example for RS232 communication and my first problem.I have this output in the terminal:5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëå˙ <00> 5 ''! Ë <00> 5 ''! Ëå˙˙˙ <00> 5 ''! Ëåë <00> 5 ''! Ëåë <00> 5 ''! ë...
