The small horizontal line marks on the TCNT0 slopes represent compare matches between OCR0x and TCNT0. To get started, you will need to get the parts that are common to all four builds, and the additional parts for the build you intend to make. The simplest model of operation is the Normal mode (WGM02:0 = 0). The MKii programmer is run from USB port, not serial - if you say Serial that is generally understood to mean a 9-pin RS232 type port, just to stay in synch on terminology. I made a shield for the Arduino as well. The counter counts from BOTTOM to TOP then restarts from BOTTOM. The synchronization prevents the occurrence of odd-length, non-symmetrical PWM pulses, thereby making the output glitch-free. Similarly to serial protocols, radio modules use their own set of protocols to communicate, such as HTTP, MQTT and UPD. For the following half-second or so, the bootloader is running on the Uno. Need any help with your board please get in touch with the official Arduino User Support as explained in our Contact Us page. I just wanted to use the Arduino Uno as the programmer for a standalone 328P chip. If the interrupt is enabled, the interrupt handler routine can be used for updating the compare value. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload. I still don't think anyone understands what I am trying to do here. There are no special cases to consider in the Normal mode, a new counter value can be written anytime. If low power consumption is the highest priority for your application, then the last method would be your best solution. The Timer/Counter Overflow Flag (TOV0) is set each time the counter reaches BOTTOM. The fast Pulse Width Modulation or fast PWM mode (WGM02:0 = 3 or 7) provides a high frequency PWM waveform generation option. I have already done this for an Attiny85 chip. The counter will then have to count to its maximum value (0xFF) and wrap around starting at 0x00 before the compare match can occur. Crazy Engineer. Well, 8 MHz needs a fuse change - as delivered from the factory, they are set to 8 MHz and divide by 8 fuse is set for the clock, so they run at 1 MHz.
