Code Examples
The following applications are provided to demonstrate the typical or interesting usage models of one or more peripheral libraries.
| Name | Description |
|---|---|
| Cache maintenance | This example shows cache maintenance operation by cleaning and invalidating the cache for the DMA buffers located in the cacheable SRAM region |
| Clock configuration | This example application shows how to configure the clock system to run the device at maximum frequency. It also outputs a prescaled clock signal on a GPIO pin for measurement and verification |
| FLEXCOM SPI EEPROM read write | This example application shows how to use the flexcom module in SPI mode |
| FLEXCOM TWI (I2C) EEPROM | This example application shows how to use the flexcom module in TWI mode |
| FLEXCOM USART blocking | This example application shows how to use the flexcom module in USART mode |
| FLEXCOM USART interrupt | This example application shows how to use the flexcom module in USART mode |
| FLEXCOM USART ring buffer | This example application demonstrates how to use the FLEXCOM peripheral in USART ring buffer mode |
| HEFC flash read write | This example application demonstrates how to use the HEFC to erase and program the internal Flash memory |
| HSDRAMC read write | This example application demonstrates how to configure the HSDRAM interface to write and read from the SDRAM memory |
| MCAN FD blocking | This example shows how to use the MCAN module to transmit and receive CAN FD messages in polling mode |
| MCAN FD interrupt | This example shows how to use the MCAN module to transmit and receive CAN FD messages in interrupt mode |
| MCAN blocking | This example shows how to use the MCAN module to transmit and receive CAN messages in polling mode |
| MPU cache coherency | This example shows how to maintain cache coherency by allocating DMA buffers in non-cacheable SRAM region defined by MPU |
| PIO interrupt | This example shows how to generate GPIO interrupt on switch press and release, and indicate the switch status using the LED |
| PIO polling | This example shows how to poll the switch input, and indicate the switch status using the LED |
| PWM Generation | This example shows how to use the PWM peripheral to generate 3-phase PWM signals with dead time |
| RTC alarm interrupt | This example shows how to use the RTC to configure the time and generate the alarm |
| RTT periodic interrupt | This example shows how to use the RTT to generate periodic interrupts |
| Systick periodic interrupt | This example shows how to use the SysTick to generate periodic interrupts |
| TC capture mode | This example shows how to use the TC module in capture mode to measure duty cycle and frequency of an external input |
| TC compare mode | This example shows how to use the TC module in compare mode to generate an active low, active high, and toggle output on compare match |
| TC timer mode | This example shows how to use the TC module in timer mode to generate periodic interrupt |
| TCM cache coherency | This example shows how to maintain cache coherency by allocating the DMA buffers in the Tightly Coupled Memory (TCM), which are not cacheable |
| TRNG random number | This example shows how to use the TRNG Peripheral library to generate and read a random number |
| XDMAC memory transfer | This example shows how to use the XDMAC peripheral to do a memory to memory transfer and illustrates the usage of burst size to reduce the transfer time |
