Probably 100% sure its the same USB to PC cable I used before so that means it has the TX/RX connections.ĭoes anyone understand the mystery and have assistance. Still the PORT selection is greyed out in the IDE. So I've downloaded the Silabs driver for the CP210x family of USB to UART bridge chips as the most likely type, installed and rebooted (that is listed here ESP32 USB-UART list.) This is also the chip family most referred to in the arduino and some other fora I consulted. The solution its to file->preferences->more preferences in arduino.txt, click the link, close the ide, and edit bug rate to 'bugrate9600'. When I try to up load a program, it says 'serial port COM1 not found'. I have downloaded and used Arduino IDE v1.8.4 from official site (needs no install) for windows10, and connected my random board with a ch340, but its LED is only blinking and I cant select the port (ie. The serial monitor will give an exception, upload will fail and 'serial port' in the menu will be greyed out. As stated in the title, the serial port option in Tools is grayed out. There is no number on the chip on the board and the espressif schematic for the ESP32 does not show what the chip type is that is on the board nor is there a list of components (apparently its not consistent which chip is used) I have an Arduino Uno connected to Windows 8.1. Its laready loaded wiht a sketch from under W7. It worked on W7 Arduino IDE 1.8.12 - but on W10 (which I swapped over to, BMFFIHS!) the COM port selection in the TOOLS tab is greyed out. When I go back to Arduino IDE to try to pick a port and it is grayed out and inaccessible. I have an esp32-wroom-32 ( espressif) as well. I came back to it later and now I have no port available at all. Raspberry Pi Weather Station Uses One Sensor, Displays Data. My question is related to this earlier today post from but its a new question, My preferences.txt file used by the Arduino IDE: Ive tried to update / delete and reinstall the driver for the board ( I will admit, I am not sure which driver is the right one for my board) but I have never gotten this to work right. In the latest issue of HackSpace magazine, out now, Phil King show you how.
