Re: Event Log Embedded

Thanks Martin, Yeah, I've allocated a Circular Buffer only for this purpose. Only problem now when simulating is when I use the function GetString() and say read 30 characters, the string comes back OK, but the data in the buffer seems to be set back to 255 (empties the data on those 30 characters) ...

Event Log Embedded

Hi all, I'd like to keep an internal logfile for debug events that I trigger on different parts of the program. The log would be kept in RAM so it can be retrieved at any time later either through serial or via the LCD. I think 100 lines of 40 characters each would be enough ~ so about 4KBytes alloc...

Re: ESP32 Timer compiler error

I had the same issue when I started using ESP32. However I've managed to adapt my program to use custom timers with some variables with minimal code. In other words, you can use a let's say 1ms Interrupt which is what I use at the moment. Inside the Interrupt routine, you just add something like thi...

Display BMP on ILI9341

Hi there guys, I'm trying without luck to display a bitmaps on an ILI9341 SPI LCD, just simulation at the moment. But doesn't seem to work at all. I've tried different file formats without luck. Is there any way to have a look at the component to see if we can adapt it to take PNG files as they util...

Custom Font for gLCD Font Library

Hi all,

Is it possible to do a custom font as part of the gLCD Font Library Component?

If not out of the box, would it be possible to get a copy of the Component to modify it to our needs?

Cheers!

Re: I2C on ESP32-WROOM-32 BUG

Thanks Martin, I don't get any errors on the console... strange. The scope capture is single shot of the first frames sent, so def. a bit weird that output... I also have nothing else on the bus, I reckon the WROOM32 board has an issue, I have plenty of them, so will try another one and get back wit...

Re: I2C on ESP32-WROOM-32 BUG

"20 - should be replaced by FCLsz_BUFFER....." I have checked the C code and this line is present in the C code output generated: // .Return = cal_i2c :: Transaction_Write(.Buffer, .Length) FCR_RETVAL = FC_CAL_I2C_Transaction_Write_1(FCL_BUFFER, 20, FCL_LENGTH); How can I fix this moving forward or ...

Re: I2C on ESP32-WROOM-32 BUG

Hi Martin,

Thanks for your efforts. Have you tried the same GPIOs I've used? If I use software mode all works fine with the slave address 0x88 I am using.

Re: I2C on ESP32-WROOM-32 BUG

Hi Martin,

Thanks for your lines. The speed is set back to 100KHz, I was trying different speeds to see if there would be any difference, but same issue.

I've also added a loop at the end and just tested the lst program on hardware, confirmed the same issue I'm afraid :-(

Cheers
