Re: OpenOCD JTAG stopped working after Win10 uprade

Managed to fix this by ussing OpenOCD suppied with the new V4 tool chain v0.10.0-esp32-20190313 (2019-03-13-09:57) now it works again, but only if you use the WinUSB driver (not libWinUSB WinLIB) .


The error still comes up but the new version gets past this and makes the connection

OpenOCD JTAG stopped working after Win10 uprade

the ESP32 version of OpenOCD (0.9.0 ) no longer finds my ESP32 DevKit or Olimex Tiny-H, was fine before recent Win10 upgrade. With max debug all goes well until it tries to talk to the driver bin\openocd.exe -d3 -c "gdb_port 51558" -c "telnet_port 51559" -f olimex-arm-usb-tiny-h.cfg -c "adapter_khz ...

First I2C transaction is at wrong speed

IDF V 3.2 When running I2C even when rate set to 100KHz first transaction is at >1MHz. If you do a fake 1st transacton it sorts itself out and rate is fine after Using code below // I2C.h #pragma once #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "freertos/event_groups.h" #inclu...

ESP32 Wroom 4.1, spi_master no longer drives display

Since moving to Cmake and using the provided spi-master examples in the sdk the TFT no longer works. It just flashes sporadically.

Tried with the latest version of the tool chain from esp-idf_tools-setup 2.0

Re: esp_ble_gatts_create_attr_tab() with multiple Services

Many thanks, the only links I could find were creating a single service, which was not my issue, if you could point me in the right direction that would be great. I solved this by making a separate per service table and then called esp_ble_gatts_create_attr_tab() & esp_ble_gatts_start_service() for ...

Is there a function like esp_ble_gatts_get_attr_value() which rather than pulling the value using a handle allows me to get the original UUID I submitted when creating the characteristic? If not whats the best wa...
