I will find a nicer way to handle it later. To put the file at the correct location, do the following. Handheld Spectrum Analyzer Tiny TinySA 2,8' LCD 100kHz-960MHz Touch Control. Available for 3+ day shipping 3+ day shipping. Another way is to connect USB_DP to PA10 directly and use PA10 to control USB connect and disconnect.īecause edy555's ChibiOS/os/hal/ports/STM32/LLD/ADCv3/hal_adc_lld.c is not updated with ADCv3 protocol, I modified and name it as hal_adc_lld.c.fixed. 50KHz-1.5GHz Vector Network Analyzer NanoVNA-H4 4 Inch LCD Screen Antenna Analyzer New. AT power-up, PA10 will pull down USB_DP then release to inform host a device is plugged in. Also, the USB_DP pin has a 1.5K ohm pull up resistor connected to VDD (3.3V), and the USB_DP (PA12) is shorted with PA10. The current test board has the MCU STM32F072CBT6 replaced by STM32F303CCT6.
VNAs ownership is now viable for students, faculty, universities, and anyone interested in electronics design work. The nanoVNA units have been brought to the commercial market at a price point (35-150) and performance point (10 kHz to 1.5 GHz coverage) combination that is very attractive. Please refer to original NanoVNA page for detail preparation information. Vector Network Analyzers (VNA) labeled the nanoVNA1. For detail information, please refer to the original project page by edy555. The device uses a rechargeable battery if you need to haul it up to an antenna tower, for example. The benefits are larger SRAM 40KB from 16KB, larger flash 256KB from 128KB, faster CPU clock 72MHz from 48MHz, and floating point accelerator. NanoVNA is tiny but sweeps from 50 kHz to 900 MHz and has a touch screen. This is my attemp to port the STM32F303CCT6 to this popular NanoVNA project.
