Audio "popping" during stereo playback and Pass-through recording not working

5

This library is quite an achievement in a limited cpu! I am using a mega. The following pcmConfig.h is in use: #define buffSize 254 #define SD_FULLSPEED #define SDFAT #define STEREO_OR_16BIT...

Arducam OV2640 auto set light mode produces an image with poor colour, poor contrast and poor brilliance.

1

OV2640 set light is defined as ``` void ArduCAM::OV2640_set_Light_Mode(uint8_t Light_Mode) { #if (defined (OV2640_CAM)||defined (OV2640_MINI_2MP)||defined (OV2640_MINI_2MP_PLUS)) switch(Light_Mode) { case Auto: wrSensorReg8_8(0xff, 0x00); wrSensorReg8_8(0xc7, 0x00); //AWB on break; ``` Unlike the...

"Centering" the stepper motor

I wanted to set the start position of the stepper and attached an opto sensor to allow the stepper motor to be moved until a hole in a rotated cardboard...

newMoveToDegree Int overflow in toStep variable

3

int toStep = deg * totalSteps / 360 does not create correct value Solved using: ``` void CheapStepper::newMoveToDegree (bool clockwise, int deg){ // keep to 0-359 range if (deg >=...

After any move the stepper remains in a high current state

3

My stepper draws 200mA when moving and **370mA when the move has completed**. It would be useful to have an idle call which sets the stepper control lines to zero:...

If toStep is less than stepN the move to is incorrect. This also affects newMoveToDegree. My solution: ``` void CheapStepper::newMoveTo (bool clockwise, int toStep){ // keep toStep in 0-(totalSteps-1) range...

Sector delete of sectors 0a and 0b fails

I am using an AT45DB161E. After reviewing the manual I can not find any significant difference to the AT45DB161D Sector erase works correctly with blocks 1 to 15 and **not...

Example code for UTFT, UTFT_SD.Jpeg does not work for LANDSCAPE

5

The example works perfectly for all of the supplied images in PORTRAIT. If myGLCD.InitLCD(LANDSCAPE); is used the image drawn is not correct. Is this a problem with renderJPEG ? Can...

Your library is very useful, thanks. The rds transfer functions are particularly useful. There is probably work to do on checking whether the rds is a) Error free b) Relevant...
