The CircuitCo Audio Boosterpack for the TM4C123 Launchpad that is referred to in the book 'Digital Signal Processing using the ARM Cortex-M4' never went into full-scale production. I have just ...

about 5pcs IC I2C can not ACK from BQ27426,It get ACK OK after I2C add 1M pull down resistor,we test I2C sequency and it is OK. For normal operation, it is necessary to use the recommend 10k-Ω pull up ...

we have a microelectronic system which draws power from the REG1 configured to supply 3.3V when the battery pack is connected. However, when the battery pack is not connected, we will supply 3.3V from ...

On the frontpage of the data sheet is a simplified schamatic which shows two resistor at OSCinP and OSCinM to ground. But if I check on page 61 (Figure51. TypicalApplicationSchematic), there is a 100 ...

The following two ISRs have different PIEACK clearing methods. Writes of 0 are ignored in PIEACK registers and hence both the methods are doing the job. Method 2 is better as method 1 is doing ...
