Re: gptimer high irq priority

The irq function has to be called directly, not via the driver. This is why this function needs to be in assembly with a rfi at the end.
There are some examples that couple a GPIO to this function.See https://esp32.com/viewtopic.php?t=28008
But how to do this for the timer?

gptimer high irq priority

Hi, I want to use gpTimer 0 for high prio irq. The irq handler (assembly) is called, but after rfi i get an unhandled kernel error. I have set the timer for Freertos to timer 1. I hope someone can help. My very stripped down C code: #include "driver/gptimer.h" void xt_highint5( void); void RegisterI...

SNTP and static IP

Not the first post about this: I have set dhcp off, set IP, mask and gateway. Set sntpservers to "8.8.8.8" and " 1.1.1.1" From the ESP i can ping these addresses, so the gateway is ok. No time. What am i missing? I "solved" the problem by starting with DHCP, getting the time, and moving to a fixed I...

which compiler for ADF

Hi,
Do i have to install the (msis201810001) toolchain to use the ADF or only the 3.2.3 IDF ?
When will the ADF be updated to use 4.x IDF?

Re: JTAG debuggers

HI I have good results on my Linux PC using Wroom32, a FTDI C232HM JTAG cable and the latest IDF. I had to add "ftdi_tdo_sample_edge falling" in the esp-wroom-32.cfg. But I still need the capacitor at the IO13 pin, see my previous post. And 10k resistors to GND at IO13 and 14. I use Eclipse and a GD...

derivate wifi certification WRoom32

According to: https://medium.com/the-esp-journal/wi-fi-certification-with-esp32-311e09dd06ff We can use the derivate certificate without further wifi-testing.

Re: ESP32 GeekWom board I2c not square and wrong freq: Picture

Hi,
You need pullups 2k2 to 10k on both I2C lines. internal pullups are to weak.
Dont know what causes the frequency deviation.
