Re: Serial strange behaviour

In France, our electricity provider send power consumption using serial at a speed of 1200. It sends data continuously. I only want reading. Thank you for syncmode implementation. I'm going to read about this mode into libs that you mentioned. This code is working when I send char one by one : ZUNO_...

Re: Serial strange behaviour

I tried some sketchs. I think it's easier to code my own than to adapt existing code. I connect rx on pins 16-17. First one is used as fast reading. Second one is used as falling detection. A falling edge starts the gpt timer. The handler of the gpt timer reads 10 bits (start bit, 8 bits of data and...

Re: Serial strange behaviour

AltSoftSerial library seems nice : https://github.com/PaulStoffregen/AltSoftSerial.

However, it is based on an frequency timer (FTM) or an interrupt register (ICR).

What is the easy way to adapt this library ? Is FTM close to GPT ? Is there any ICR available on Z-UNO ?

Best regards.

Re: Serial strange behaviour

argh! I just saw on Reference page that 9600 is the minimum speed accepted. Sets the data rate in bits per second (baud) for serial data transmission. For USB baudrate is fixed on 115200 bps, on UART it is possible to select baudrate. Valid values are: 9600, 14400, 19200, 38400, 57600, 115200, 23040...

Serial strange behaviour

Hello, I suspect an issue using baudrate less than 9600. Let me explain some cases : Case 1, 2 and 3: Z-Uno connected to PC using Serial int ByteReceived; void setup(){ Serial.begin(9600); } void loop(){ if (Serial.available() > 0){ ByteReceived = Serial.read(); Serial.print(char(ByteReceived)); } }...

Serial parity

Hi, Z-Uno is awesome. I hope I will migrate from Raspberry to Z-Uno. I'm unavailable to read Serial1 properly. I get following result : DEC BIN BIN HEX CHAR 252 1111111111111100 1111100 7C | 252 1111111111111100 1111100 7C | 248 1111111111111000 1111000 78 x 192 1111111111000000 1000000 40 @ 224 111...

Re: oled issue SSD1306

Yeah, working much better with 0x3d i2c address! Thank you! If everything was so easy to solve :)

I didn't set the reset pin. Is this a good solution ?
I'm wondering if we can make text font bigger (as we can do with numbers) ?
