Hello, how to let touchgfx font support emoji unicodes?

FSMC with NAND interface signalling

2020-05-18
Hello, I am using STM32L4R9AI (attached the reference manual) with 128GB NAND flash (MT29F128G08CFABBWP-12IT:B TR) (attached its datasheet).1- This is 8bit NAND flash and according to page 104 in the reference manual the last signal is NWAIT/INT whic...

ADC power circuit

2020-05-14
Hello, I am developing a circuit using STM32L4R9AI, VDD = 1.8v, VDDA&VREF+ = 3.13v, according to ST hardware design manual (I attached) for a better power filtration there should be bead between VDD and VDDA, will that create a problem given the volt...

ADC voltage with respect to MCU VDD

2020-03-04
Hello, I am using STM32L4R9AI, the MCU VDD is powered at 1.8v and VDDA at 3.3v. in the recommended design by ST, there is ferite bead between MCU VDD and VDDA, ferite bead is basically inductor which acts as short circuit for DC current, so how can I...

STM32L4+ power scheme design while working at 1.8v

2020-03-02
Hello, I will use STM32L4R9AI in a battery powered design with PSRAM that powered at 1.8v and flash memory that can work at wider voltage range (in addition to DSI display, RTC, ADC, DAC, USB, I2C) so my power scheme is as following:MCU:VDD : 1.8vVDD...
