It hasn’t been working for me, I get this error:
error: espcomm_upload_mem failed
I have programmed at least one of these ESP-01s before. I got them from Addicore:
I am using this programming adapter which I have 2 of:
The error message is the same with both programmers. I am using an Adafruit FTDI cable that works with other boards.
I am using the following settings on the Arduino IDE:
Board: Generic ESP8266 Module Flash Mode: DIO Flash Size: 1M / 64k Debug Port: Disabled Debug Level: None Reset Method: ck Flash Frequency: 40MHz CPU Frequency: 80MHz Upload Speed: 115200 Port: COM4 Programmer: AVRISP mkII
For 2 of the ESPs the red and blue leds are on steady. For the third the red is on steady but the blue is flashing ~ once per second.
A very strange thing is happening for the 2 that have steady on blue leds, if I plug them in, the mouse cursor, in windows, jumps to the right about 3 inches every second or so making it impossible to do anything with them.
