Re: ESP32 Firmware Protect

Many thanks Martin,

it looks a bit more complex then I thought. It seems that I have to Update my ESP‑IDF from 4.x to 5.x.

Are there any issues involved in relation to Flow Code with such a ESP‑IDF Update?

ESP32 Firmware Protect

Hello Flow Code Community,

a short question for ESP32. Is there a way to protect my firmware on this chip? In my old PIC days I did it via the compiler chip setting inside FC.

Re: ESP32 and I2C CAL component Problem/Observation

....transaction OK. Yes a example would be cool too.

In between I´ll checked the transaction hardware. Great it is working with the correct clock frequency.

Re: ESP32 and I2C CAL component Problem/Observation

Hi Martin,


fc file attached. In between I´ll checked I2C master component and I2C CAL component. Same result. Running only in software mode not hardware. Clock frequency approx 500Hz.

ESP32 and I2C CAL component Problem/Observation

Hello FC Team, today I made the follwing observation with my ESP32 and using I2C CAL component. First of all the I2C CAL is only bringing data in Software mode on the I2C bus. Hardware mode either Ch1 or Ch2 will not bring any data on the bus. Unfortunately the clock rate is wrong in software mode w...

Re: ESP32 WLAN init and BT init Problem

Hello Stefan, Hello Ben, I can report that the fix from Ben is working. I can compile now with WLAN and BT init together. FC_WLAN_BT_init.png This for the main reason that I can not tolerate a 2.4GHZ emission from the ESP32. LOL I will see if I can monitor a difference in the emission spectrum with ...
