Programming the ESP32 with the Arduino IDE

The code programmed for the ESP32 by using the Arduino IDE can be used directly on the Arduino UNO? I read a weather station article that was done with ESP32 but compiled with Arduino IDE, I have an Arduino UNO board, can I just

3S LiIon BMS ESP 32

against total discharge and Short circuit and what else you need to protect. Also I want to use my ESP 32 to query the charge status of the battery pack. Unfortunately, I don't know whether a BMS is also there to charge the batteries and whether you need battery balancing. I am brand new to this topic

Hardware-independent µC core?

Hi, the problem: my code wants to run on a couple disparate microcontrollers (ESP8266, "small" STM32, AVR AtMega). Besides the usual digital I/O which e.g. Arduino supports cross-platform I need stuff like port interrupts, timer interrupts, and letting the controller sleep until

How to adjust WiFi-channel for ESP-NOW

using. But I didn't find anything about hwo to adjust the Wifi-channel with ESP-NOW. Does anybody know how this is done for ESP8266-modules. ESP32 uses a different library so you can't jsut look up ESp32 and copy it for ESP826. Hallo, ich probiere gerade zwischen zwei

wie der der mit dem WiFi-Router verwendet wird. Ich habe aber nichts darüber gefunden wie man bei ESP-NOW fr ESP8266 den Kanal einstellt. Bei ESP32 wird eine andere Library benutzt. Deswegen kann man die Erkenntnisse von ESP32 nicht auf ESP8266 übertragen. Jedenfalls nicht alle. Weiß jemand wie

suggestions. What if I built the processor with VHDL. Then the processor interface with modules like the ESP32 for wifi and bluetooth.

Then why the FPGA? The ESP is able to handle the whole job...

MCU with WiFi and GREAT ADCs

have been looking all over the Internet and the MCU that best matches what I'm looking for is the ESP32. However, those ADCs specs are not enough for my project: I'm in need of a Microcontroller that has WiFi (integrated 2.4GHz antenna) and at least 12 input ADC pins (>=12 bit precision) with high

breakout board for <15€. I would use an esp32/8266 with an external ADC (breakout board if you want to), also because the Wlan could disturb the ADC measurements and add noise.

what is difference between arm-elf and arm-eabi?

Codesourcery package has been the only one which offered Cortex-M3 support and AFAIK Ride supports STM32 too. Just speculation, I have never used the Ride tools. I don't know "Sarm" so I can not comment on it at all. > All others would fail in different > ways. You did not write the error-messages

small and porting code between them is rather easy. Porting code from IAR to GNU is a more difficult esp. if the EWARM compiler-extension have been used.

run code faster

mesaure any code execution with osciloscope and some time in us. There is some overhead in "pin-toggle" esp. when using "legacy" GPIO. On LPC214x FIO is available which is faster. Try to determine the time-overhead for GPIO-access first with a simple loop that just toogles a port-pin and take it into account

enable the MAM? Flash-access on LPC2000 with activated MAM is rather fast but RAM is still faster esp. if there is a "cache miss" during flash-access. You can execute code from RAM esp. time-critical functions. > I try Optimization change (now is 5) and do efect or code do not run. Do you mean -

about uclinux. There are currently just too many other things to do. So please send what you find out esp. information about cross-toolchains (building them or ready/made) which can be hosted on MS-Windows without emulation-layers or virtual machines.

Just realised that codesoucery now do a prebuilt native win32 uclinux/uclibc based toolchain - http://www.codesourcery.com/gnu_toolchains/arm for details. Building your own is possible however. You will also need a lot of flash and ram on your board, uclibc

answer for some time: This forum might not be the best place to ask a question about the IAR EW. Esp. the debugging-functions and the debugger-setup are very toolchain/IDE-specific. Since you are using a commercial product you might ask the tool-vendor's (=IAR) support. Martin Thomas
