Re: [NOTES] Multi Core support

Hi, Just my 2 cents. Software running on hi-end cores would run Linux, Android, Windows ,....to benefit from existing softwares, packages, stacks,... ChibiOs, any other RT kernel, would run on the Cortex-M cores to handle ..... the real time stuff :D So, for these kind of devices and OSes, there is ...

Re: Raspberry Pi port

Hi Just my 2 cents. RTOS on a quad core 1+GHz. What realtime application will be targeted by this? Something complex, which will probably need lots of serial ports, SPI, I2C, Timer modules "STM32-like", PWM, CAN, encoders counters. Am I wrong if I say RPi processor is not the best choice i...

Re: STM32F2 lwIP client Topic is solved

Hi,

ESP32 also uses LWIP. You will find plenty of examples.

Re: I2C err

From the message "i2c_lld_master_transmit_timeout" you could find the possible cause in the source code. My guess is your peripheral is not correctly receiving, and it is not answering the read/write request => timout. The peripheral address could be also wrong. Check if the address is not...

Re: I2C err

Resistors needed on both I2C pins.

Re: NIL winout HAL with NVIC problem

Juste my 2 cents.
I would prefer starting from a CM3 project, for STM32F10x, with everything correctly configured for the core, peripherals, vectors, compiler options, linker,....
And then copying from the CM0 project the code I need.

Re: Sensors Reading-STM32F303

Hello Samir, Your data is simply sent to the USB serial port. Use a terminal program on your PC, connect to the COMx port with the corresponding baudrate, parity,... and your data will be displayed on the screen. Only displayed, not recorded. To put your data in a file, you should use a terminal pro...

Re: L432KC i2cMasterTransmit freezes

Hi Raul, I had the same problem on both the nucleo446 and NucleoL432. CAN needs stable and precise clock, and internal RC set to run at full speed is not good enough to ensure these timings. On STM32F446, using RC, I had to slow down to about 80MHz core frequency to have CAN correctly working. But a...

Re: L432KC i2cMasterTransmit freezes

Hi,

I also used the Nucleo432, connected to 4 MCP23017 (I/O ports). I used external 2k2 resistors and connection was fairly easy.
But as I also used CAN, the STM32 is not running at full speed, due to timings problems when used with internal RC.

I will post the code when I go home.
