Re: NuttX question

With pixracer (hardware for pixhawk v4) officially support esp8266, and esp32 support NuttX... Is Espressif considering making an custom pixhawk flight controller? Just throwing ideas.


Best,

Re: NuttX question

I am excited to see that esp32 is natively supported on board-specific level for NuttX RTOS. Although it seems outside the scope of this forum, but may I know how to get started on writing the configs for an custom board with an unsupported MCU? I am using STM32F427II and wish to burn a NuttX RTOS. ...

Re: Question about esp32 Flash download through JTAG

May I get an updated timeline for JTAG flash?

Also I am curious about changing the registers and variable values while running "make monitor", is that possible through current JTAG debugging process?


Thank you,

Beck

Re: About the CAN controller.

Things didn't go that well on me. I've built the PCB with Texas Instrument SN65HVD232, and got the code built, and measured the CAN_H and CAN_L in recessive state of 2.285V so I believe there are no power issues. Running Rudi's main file, and when I try: ESPCan configured by this Data: Node : 0x264 ...

Re: Programming in C++

Hi ESP_igrr and kolban, May I know the current process to support C++11 thread/concurrency library? I wish to perform matrix operations in ESP32, and C++"Eigen.h" library would be a good fit. Eigen does depends on a C library called LAPACK, but I failed to link the library to my program, a...

Re: About the CAN controller.

Thank you Rudi for the explanation! I will test my board out and see the result.

Thanks iosixllc for the head up.

Re: About the CAN controller.

Hi Rudi and Thomas, It's great that you complete the CAN bus driver for ESP32! When I configure the driver with different pinout, in my case is GPIO5->CAN TX and GPIO16->CAN RX, the menuconfig shows they are invalid pins. Running the code on both device successfully, but no communication yet. Is the...
